[Boost-users] boost::asio::read_until Segmentation Fault & Third Party Signal Handler

My Linux application sis using bool::asio::read_until() to read data from a socket.  The application also uses commercial, 3rd party hardware.  Occasionally my program crashes due to a SIGSEGV violation.

The core dump stack trace is shown below.  It indicates that the 3rd party signal handler is invoked while my thread is waiting for socket I/O, and that the crash is occurring during signal handler execution.

While I recognize that this is an issue with the 3rd party vendor (and I am currently engaged in discussions with them), I'm wondering if my usage of boost is incorrect, or if there is something that I should be doing differently in performing socket I/O?

I am using boost v1.43.
